osutil: cleanups

- use tabs
- eliminate old-style function pointer calls
- eliminate weird scoping
- eliminate assignment-in-iff
- use !foo rather than foo == NULL

#!/bin/sh

mkdir a
cd a
hg init
echo foo > b
hg add b
hg ci -m "b" -d "1000000 0"

chmod -w .hg/store

cd ..

hg clone a b

chmod +w a/.hg/store # let test clean up

cd b
hg verify
